Full textThe gut microbiota constantly interacts with the host. It communicates directly with neighboring intestinal cells as well as with distant organs, including the brain. As a result, the microbiota regulates numerous biological processes and is involved in the pathophysiology of many diseases.We first investigated whether commensal bacteria from the gut microbiota modulate an essential post-translational modification in intestinal physiology, i.e. SUMOylation. It has been demonstrated that gut commensal bacteria can promote SUMOylation through the production of short- and branched-chain fatty acids (SCFA/BCFA). In the present study, we demonstrated that the commensal bacterium Staphylococcus warneri secretes a protein, named Warnericin RK, which targets key components of the SUMOylation machinery, leading to a decrease in intestinal cell’s SUMOylation. This decrease in SUMOylation promotes gut inflammation, and more particularly TNF-dependent inflammatory responses. Collectively, these findings highlight the versatility of mechanisms used by non-pathogenic bacteria in the gut microbiota to regulate host SUMOylation. Additionally, they show that changes in the composition of the gut microbiota may have an impact on gut inflammation by modulating the equilibrium between bacterial effectors enhancing or suppressing SUMOylation.Secondly, we investigated the role of the gut microbiota in the pathophysiology of Binge-Eating Disorder. Indeed, the microbiota is involved in the regulation of eating behaviors through communication along the gut-brain axis. Consequently, it has been hypothesized that the microbiota may be a contributing factor to binge-eating disorder. To investigate the potential causal role of the gut microbiota in this disease, we have transplanted fecal microbiota from patients to recipient mice. Our experimental model did not allow us to demonstrate a role for the microbiota in changes in eating behavior, or in the gastrointestinal and anxiety-depressive disorders associated with binge-eating disorder
